That's the interview. He said if fans theorize what he's going to do, he'll change it. He also said he'd change the entire ending of the story if the fans predict it, and he's has this ending planned out since day one. Oda just does not like people being able to guess what he's going to do. Which is why he always makes things seem like they are going to go one way, and then does something completely out of left field that nobody expects.
The way I look at it is, if Zoro joins in on the fight against Kaido, then he will not be getting a 1 on 1 fight against any High Tier character, because there is no way he's going to be in any condition to keep fighting if he is just coming off a battle against a Calamity. So the fandom needs to ask themselves, which they want to see. Zoro vs King, or Zoro helping Luffy fight Kaido.

And alSo, good lord... Oda is not omnipresent on the internet, it’s probably the editors telling Oda what fans think on the internet
